[The Conversation Africa] Tomás Saraceno In Collaboration: Web(s) of Life, which opened at London's Serpentine South Gallery in June, explores how humans relate to spiders. It features installations of spider webs displayed and lit to be viewed as sculptures. There are also films: one made about Saraceno's work with groups battling lithium mining in Argentina and another about spider diviners from Somié village in Cameroon.
